vscode c++解决包含头文件红色波浪线问题

安装c/c++插件后，按ctrl+shift+p，

点击打开了c_cpp_properties.json文件，对其中的IncludePath进行编辑，示例如下：

"includePath": ["${workspaceFolder}/**","${workspaceFolder}/include/**","${workspaceFolder}/src/calc/include/dbus/**","${workspaceFolder}/src/calc/include/util/**","${workspaceFolder}/src/calc/include/main/**","C:/mingw32/i686-w64-mingw32/include/c++","C:/mingw32/i686-w64-mingw32/include/c++/i686-w64-mingw32","C:/mingw32/i686-w64-mingw32/include/c++/backward","C:/mingw32/i686-w64-mingw32/include","C:/mingw32/include","C:/mingw32/lib/gcc/i686-w64-mingw32/5.4.0/include","C:/mingw32/lib/gcc/i686-w64-mingw32/5.4.0/include-fixed"],

注意，如果a.h中还include了b.h，即使a.h在包含范围内，但b.h没在包含范围内的话，a.h上也仍然会显示波浪线。
